SAMUEL ORUMP, or MONTOLAIR, NEW JERSEY.

BRONZlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 244,195, dated July 12, 1881.

Application filed June 1, 1881.

To all whom it may concern:

Be it known that 1, SAMUEL GRUMP, of Montclair, in the county of Essex and State of New Jersey, have invented a new and useful 1m provement in Bronzing-Machines, of which the following is a specification, reference being bad to the accompanying drawings.

The invention has relation to an improved bronzing-machine, the object being to provide means of dusting or brushing the sheets after the bronze has. been applied.

The distinctive novelty of the invention consists in the employment of a roller or rollers to which are attached or applied pieces of cloth or rags,.or other soft material, the ends or edges of which are so arranged that they strike upon the bronzed surface, and thus remove the particles of bronze which are not held in place by the sizing. The operation of a roller provided with a cloth or rag having a free edge or end is more satisfactory than that of any known brush. The removal of the particles'of bronze is much more rapidly and completely effected, and the result is better in other respects.

In the accompanying drawings, Figure 1 is a perspective view, showing the position in which my improved rollers are placed upon an ordinary cylindrical bronzing-machine. Fig. 2 is a detached sectional view of a part of Fig. 1. Fig. 3 is a longitudinal section of a roller. Fig. 4 is an end View of one of the rollers.

A A denote the rollers to which the cloth or rag is secured, as shown in Figs. 1 and 3. In the present instance they are of elliptical shape, which is desirable, in order to give the cloth or rag an irregular action, causing it to beat or strike the bronzed sheet at short intervals. The rollers are connected with a motive power so as to be rapidly rotated, by preference, in different directions. In the present instance I have shown two rollers, but a satisfactory result may be produced when but one is used. The rag or cloth will be secured to the roller in any convenient way, and will consist of any suitable soft textile or other flexible material, the only essential consideration being that one edge or end be permitted to remain free, so that (N0 model.)

it will beat or strike the bronzed sheet when the roller is actuated.

The preferred method of constructing the roller A is as follows: I take a plain shaft, and upon one end of it place a collar, a, havin g its inner face cut at an an gleof about sixty degrees. Upon the shaft I then arrange alternate layers of the elliptical or disk-shaped pieces of fabric b and the smaller similarlyformed pieces of paper, pasteboard, or other suitable material, 0, supplementing them with a collar, d, similar in size and-form to the collar to, before described. The pieces I) c assume a transverse position on the shaft and are retained by the collars a d. The pieces 0 being smaller than those lettered b leave the edges of the latter loose and pliable, while the center of the roller is compact. The purpose of placing the pieces I) c on the shaft in a transverse position is that the edges of each layer b may sweep or brush a much larger surface than it would if it were at right angles to the shaft.

I do not limit myself to a roller of any particular shape, nor to a cloth of any particular kind or dimensions; but

What I claim as new, and desire to secure by Letters Patent, is-

l. A bronzing-machine in which a roller having secured to it a piece of textile or other suitable material, one edge or end of which is free, is actuated to strike or brush the bronzed sheet, substantially as described.

2. In a bronzing-machine, an elliptical roller having attached to it a piece of textile material, one edge of which is free, for the uses and purposes substantially as described.

3. The roller A, consisting of a shaft having upon it alternate layers of material I) 0, substan tially as and for the purpose set forth.

In testimony that I claim the foregoing improvement in bronzing-machines, as above described, I have hereunto set my hand this 21st day of May, 1881.
